A comparison of radiographic measurements in normal, hallux valgus, and hallux limitus feet.

Abstract

This study investigated the differences in weightbearing, foot radiographs among normal subjects, those with hallux valgus, and those with hallux limitus. An intrarater reliability study of various x-ray measurements was conducted, utilizing seven dorsoplantar and six lateral measurements. The results showed that metatarsus primus adductus, increased metatarsal width, and a positive first metatarsal protrusion distance were associated with hallux valgus, whereas increased hallux interphalangeal angle was associated with hallux limitus.
